Embodiment Construction
[0020] In order to better understand the present invention, the present invention will be described in detail below in conjunction with the accompanying drawings.
[0021] 1. Experimental content
[0022] The internal reaction mechanism of n-valeraldehyde self-condensation to 2-propylheptanol includes two processes: one is the aldol condensation of n-valeraldehyde to obtain 2-propyl-2-heptenal, and the other is 2-propyl-2-heptenal Hydrogenation of alkenals yields 2-propylheptanol ( figure 1 ). The above two reaction mechanisms can be integrated under suitable catalysts and conditions. After regulating the aldol condensation of n-valeraldehyde to generate 2-propyl-2-heptenal, 2-propyl-2-heptenal is then added The hydrogen reaction produces products, and the two mechanisms are promoted synergistically. The rapid consumption of intermediate products can promote the reaction balance to shift to the product direction, which is conducive to improving the efficiency of the reaction...
